Whenever I have issues like this at home, I reset the router and it has fixed the problem 100% of the time.

That said, I realize that not everyone can stroll around the building at work resetting wireless routers and rebooting servers, etc., so I don't have a practical suggestion.

Klotar, thanks for the response. In fact I did reset our routers/access points. I'm unable to connect both at home with the Rogers TalkSpot router as well as at our office. I forgot to mention it during the original post. I am a seasoned IT Pro but don't have the time to delve into the inner workings of the config on the handheld running beta code nor watch the network for traffic to see what's going on. I'll just downgrade if that's what's needed. I didn't know if anyone else was running into these problems.
